Line length measurement
Lines should be separated and each line measured under a tension of 5 kg.
Measurement is made from the line karabiner to the canopy`s surface in according to
the method of certification. Measurement of brake lines is made from the knot on brake
handle know to upper loop of galery line. The lenght of bunching line is not included. Rib
numbering begins in the middle of canopy and leads to the wing tip.
Measured full lengths should be documented in the inspection record and are compared
with certified full line lengths protocol. Lengths should not differ by more than 10 mm.
The opposite sides should be checked for symmetry.
Canopy line-attachment points check
Attachment points should be checked for damage and stretching. Defects, loops and
flares should be repaired.
Canopy fabric check
Ribs, diagonal ribs, top and bottom surface should be checked. Any damage to sewing
or tears to the fabric, which could influence flying characteristics must be repaired.
Lines
All lines should be checked for tears, breaks any damage to the sheath or signs of wear.
Special attention should be paid to the sewing of the line loops. Damaged lines must be
replaced.
The results should be documented in the inspection record.
Connector check
All line carabineers, trimmers (if used), speed systems and pulleys should be inspected
for visible damage. Open or improperly secured connectors should be secured in
accordance with the producers recommendations.
Risers
Both risers should be checked for tears, signs of wear or any damage and measured
with a pull of 5 daN strength. Measured data should be documented in the inspection
record. The difference must not be higher then 5 mm when compared to specified
lengths.
Final check
The glider sticker and check sticker must be inspected for readability and correctness.
The check must be documented with date, signature and stamp on the canopy and in
the user manual.
